摘要
Following a hypothesis developed in an earlier paper, here it is discussed how deviations of blood pH from the normal range (namely states of acidemia) together with high blood levels of free fatty acids (FFA) may offer a rationale for many important risk factors for cardiovascular diseases (CVD) by shaping a context for formation of fatty acid micelles and vesicles with an acidic core, which fuse with the endothelia, disrupt vital cell processes, and thereby may initiate atherosclerotic plaque formation. Acidemia may arise primarily from dysregulation of the systemic buffers that control blood pH, chronic diseases of kidneys and lungs, inappropriate diet, or may be induced by some common drugs. The level of free fatty acids may be increased and maintained high by chronic stress, and adrenergic shocks. Elevated concentrations of blood FFA in a context of acidemia allow to understand important cardiovascular aspects: the increased risk of menopausal women, the protective effects of physical exercise, the changes in vascular behavior characteristic of metabolic acidosis/acidemia, the role of diet in the pH balance, on how some known medicines like metformin, steroids, NSAIDS, proton pump inhibitors, and calcium supplements may influence CVD risk, and an explanation is offered for the role of statins.
